I'm not sure how accurate the deck area is.
And if I had a higher resolution?
I'd give it to you in a heart beat!
It's located at

I tried several ways to increase it's size but it gets pixelated.
And I'm not good at graphs stuff sorry to say.
Wish I could offer something better.
I also found this print on E-Bay.
Not sure what they want for it.
